- the mechanism of perpetual calendar of this fifth form of execution is instantaneous, at midnight each day, and can be corrected forwards or backwards at any time of the day since it is composed only of gears.
- the sixth embodiment of the perpetual calendar mechanism illustrated in Figures 50 to 57 is also a secular calendar like the fifth form of execution. This sixth embodiment differs from the fifth only in the realization of the age-old cogwheel and only this one will be described, for the rest of the mechanism we will refer to the description of the fifth form execution, ( Figures 46 to 49).
- the age-old cogwheel of this sixth embodiment of the mechanism of perpetual calendar is driven by the four-year indexing wheel 100 whose single tooth drives at a rate of one every four years a transfer pinion 101 meshing with a transfer wheel 103 of twenty five teeth pivoted around of the axis 104.

- This additional training at the end of each month corresponds to a number of steps equal to the difference between 31 and the number of days of the current month. This additional training takes place only if the teeth of the wheel of the duration of the months 47 are engaged with the second drive gear 35.
- this wheel of dates 31 is also driven by the age-old cogwheel to delete certain leap years as in the fifth form of execution.
- the mechanism does not consists only of reversible gears and daily self-drive is instantaneous. In this way a manual correction can be done at any time, either forward or backward, without disrupting or damaging the mechanism.
- first, second and third embodiments described could also be equipped with an age-old cog and / or a display gear train of the vintage as described with reference to the fifth and sixth forms execution.
- the group of concentric mobiles including the mobile of the months is equipped with an extra wheel with a tooth of force for the drive of the age-old cog.
- This extra wheel to a tooth performs in the described embodiments a turn in four years.
- the mechanism has been described in several embodiments and variants to show the diversity of execution of its operating principle schematically with reference to FIGS. 1 and 2. It goes without saying that modifications of implementation can be made to the mechanism without leaving the framework of the claimed protection. So, there is no other way to reverse the order of certain cogs of the groups of mobiles as far as the functions are respected. It is the same with the number of teeth of certain mobiles which can be modified as long as the reduction ratio of the gear train which they participate remains unchanged.
- the multiple mobiles have been described as being formed of independent wheels made integral with each other others angularly using a pin. This pin could be replaced by spot welds or gluing them together composing the mobile. Alternatively the multiple mobiles could be made in a single piece machined and having several teeth at different levels.
- the original principle of the present invention lies, as we have seen, in the fact of driving by different ways the wheel of dates 31.
- This wheel dates 31 is driven by a first link kinematic, the direct connection, at a rate of one step per day at midnight.
- This wheel dates 31 may also be driven by a second kinematic link, formed by the catch-up train, which can be automatically put into service during the last four days of each month.
- This second kinematic link drives this wheel dates 31 of one, two or three additional steps in months with a duration of 30, 29 or 28 days respectively.
- this wheel dates 31 can also be driven with a step additional by a third kinematic chain formed by the gear train secular the first year of some centuries, 2000, 2100, 2200, 2300, 2500, 2600, 2700, 2900 etc. to remove the twenty nine of February from those years that would normally be leap, which corresponds to secular correction.
- the PTO 3 is mounted on the axis carrying the first drive pinion 9.25 and the drive tooth 2.24.
- this PTO 3 could be arranged differently, for example secured to a pinion which would be engaged either with the teeth of the wheel of the days 27 either with the teeth of the first 29 or the second 46 wheel drive only.
- This PTO 3 does not have function than to drive each day a given number of teeth one of the wheels or sprockets of the drive chain 25,29,35,46 or the wheel of the days 27.
- this PTO could include the pinion 3 integral with an actuating finger acting on a star of seven integral teeth of the day wheel 27. In this case, each day the PTO 3 causes the rotation of 1/7 of the wheel of days.
- the different mobiles can take the form of wheels or crowns, in the general part of this description as well as claims the term mobile has been used, while to define particular forms of execution these same mobiles were defined as wheels or crowns according to the achievements special.
- the control wheel whose teeth has four teeth is, as will be understood, the equivalent of the control pin or of the control crown according to the embodiments.
- this body is referred to as the command and this is only in the specific part that this controller is defined precisely as a crown, a pin or a wheel of ordered.
- the different mobile groups of mobiles can be next to each other instead of being superimposed as long as the different cinematic channels are respected.
- the display of the embodiments of the mechanism where the wheel of days, the date wheel and the wheel of the months are not concentric should not necessarily be online as illustrated. Indeed, the display of different indications, day, date, month and year in a four-year cycle can be concentric or arranged in any desired way if we add a cogwheel transmission to the wheel of days, the wheel of dates, and the wheel of the months.
- This code may include a letter A, B, C or D indicating the year in a four-year cycle, this letter being followed by a number from 1 to 12 for indicate the month.
- Such a display can be achieved by a disk carried by the wheel months, including on its periphery the indications A1 ... A12. ... B1 B12. C1 ... C12. D1 ... D12; these indications being visible one by one through a window of the dial.
- This display disc of the months and the cycle of years makes a turn in four years.
- PTO 3 can be driven by an electric motor driven by a time base or mechanical for example by a clockwork movement.
- This actuating train causes the pinion 3 of the power take-off from of a classic 140 date crown of a watch movement by through a multiplier kinematic chain.
- the internal toothing of the date crown 140 which serves for its daily actuation of a step, for example using the coach 141 driven in continuous rotation by the watch movement, meshes with a first pinion 142 secured to a first wheel 143 meshing with a second pinion 144 integral with a second wheel 145 meshing with the pinion 3 of the intake of strength.
- the reduction of this actuating wheel is such that, when the first gear 142 is driven by a step by the date crown 140, the pinion 3 of the PTO is driven seven steps or a full turn.
- the coach 141 may comprise a tooth connected to a drum by a spiral spring, drum driven continuously by the clockwork movement. During his training the drum turns and the tooth of the coach comes into abutment against a tooth of the date crown 140. From this moment the spiral spring is stretched until the moment when its strength surpasses that of a jumper which maintains the angular position of the crown 140 who then jumps one step instantly.
- the power take-off may not be a complete instant revolution a day but only one step a day to midnight. This is the case if one of the axes 26, 28 or 38 of the mechanism is actuated by a not per day of an angular value corresponding to one day. This is done for the embodiments described if one of these axes 26,28,38 carries a pinion of seven teeth meshing with for example the pinion 142 (Fig. 58). In this case the actuating train comprises only this pinion 142 driven one step per day, instantaneously, by the date crown 140.
- the PTO is in direct connection with the crown of winder R when it is placed in the time setting position so that the Perpetual calendar mechanism can also be driven manually. This link is done conventionally.
- This second embodiment of this actuating wheel of the grip of force comprises a floating ring 146 which can move in rotation and in translation around a hub 147.
- This ring has on its periphery outer abutment 148 cooperating with a locking pin 149 defining its position at the beginning of the cycle just after midnight.
- This floating crown 146 is subjected to the return action of a spiral spring 150 tending to maintain this crown in its beginning cycle position.
- This floating ring 146 also has a second internal toothing partial 152 driving at midnight the pinion 3 of the PTO 3 under the action of spring 150 and a first gear 151 which serves to wind the crown floating 146 by a mobile arming whose wheel 153 is driven at a rate of turn per day from the hour wheel 154 of the watch movement by via a mobile 155.
- the mobile armage has solidarity with the wheel 153 a coach 156 having four teeth spread over approximately 180 ° and cooperating with the first internal toothing 151 of the floating ring 146 and a solid part on the rest of its periphery whose outer diameter is greater than the one on which his four teeth are.
- the seventh embodiment of the perpetual calendar mechanism illustrated in Figures 63 to 69 has the particularity of presenting a provision concentric well suited to circular watch movements and display the day, month, and year in a four-year cycle in a single counter.
- Figure 63 illustrates three positions of the mechanism when changing from 15 to 16 month, where in the middle position the month and the year are displayed by a code A, B, C, S indicating the years within a four-year cycle and the numbers 1 to 12 indicating the current month.
- Figure 64 illustrates the mechanism of this seventh embodiment in section along the line A-A of Figure 65 which is a plan view.
- Figures 66, 67 and 68 illustrate in plan the workings of the mechanism of this last form of execution located in the lower, middle and the upper part of the mechanism, while Figure 69 illustrates the display disk of the calendars.
- the mechanism of this seventh embodiment comprises mounted on a plate 160 a central barrel 161 around which are rotated a wheel of dates 162 bearing a date disc 163, an additional mobile 164 to a tooth 165 and a control wheel 166 having four teeth.
- These three movable 162, 164 and 166 are angularly integral with each other and form a first group of concentric mobiles.
- the record of the dates 163 has the numbers 1 to 31 and inserted between 15 and 16 a notch 163a.
- a PTO 167 driven at a rate of one turn per day at midnight by the watch movement is secured to a drive pinion 169 and a 170 drive tooth.

- a retractable tooth 174 slides in this ring 173 and can be in the active position inserted after the group of two teeth.
- a third group of mobiles is constituted by a crown of the months 175 of an internal dentition of forty-eight teeth and performing a revolution in four years.
- This ring of months 175 bears on its upper surface coded indications A, B, C and S corresponding to one year within a cycle four years and four sets of numbers from 1 to 12 corresponding to the months.
- This crown of the month 175 carries a pin 176 driving a ring 177.
- This ring 177 performing a turn in four years has on its inner surface a recess 178 corresponding to 1 ⁇ 4 of its periphery.
- This inner surface of the ring 177 cooperates with the retractable tooth 174 to hold it in position active for three years then during the fourth year of a cycle, year leap, this retractable tooth 174 can retract into the recess 178 under the action of its return spring.
- the crown of the duration of months 173 has a group of two teeth and not three teeth.
- a fourth group of mobiles features crazy rotated on an axis 179 a eight-toothed gear 180 meshing with the transmission gear 172 as well a pinion of two teeth 181 meshing with the toothing of the crown of month 175.
- This seventh embodiment of the mechanism works on the same principle than the other forms of execution already described. What is different is that the wheel dates 162 has thirty two teeth and the record of the dates has the numbers from 1 to 31 plus a sector having the notch 163a. When this notch 163a is next to the single window 182 of the dial, this notch 163a reveals a portion of the upper surface of the crown of the month 175 bearing the codes corresponding to the year in a cycle of four and the current month.
- the date wheel 162 is driven by three separate paths.
- this wheel dates 162 is driven at a rate of one step per day by the drive tooth 170 actuated by the PTO 167.
- this wheel dates 162 is driven in the night of 15 at the 16th of each month by the drive pinion 169 and the single tooth 165 of the additional mobile 164 a step further. This corrects the presence of the thirty second tooth of the wheel of the dates 162 which is therefore advancing a step extra per month between the 15th and the 16th of each month. If the change of date is obtained automatically by the PTO, this process is not visible because it is done in a fraction of a second.
- FIG. 63 shows the display of the 15 of a month on the left, and the display of the 16th of the month on the right. In the middle is illustrated intermediate position between 15 and 16 where the notch 163a of the disc of 163 is next to the box 182 and where appears the code of the year in course and the current month carried by the crown of 175 months.
- This crown months 175 is driven by the transmission ring 172, the first pinion of eight teeth 180 and the second pinion of two teeth 181 which is angularly supportive.
- This 175-month crown performs a four-lap years.
- the date wheel 162 can be driven by the drive pinion 169, the crown of the duration months 173, the transfer pinion 168 and the control ring 166 from 1 to 3 additional steps depending on whether the current month has 1, 2 or 3 days less than the maximum number of thirty-one days.
- This training can not however, take place only if the retractable tooth 17 or one of the teeth of the crown of the duration of the month 173 is in position to mesh with the drive pinion.
- This kinematic connection is the driving force of catching.
- the date wheel 162 could comprise more than an additional tooth, for example four or more.
- the mobile additional 164 has a number of teeth 165 equal to the number of teeth of the date wheel 162.
- the date disk 163 then has a number of notches 163a equal to the number of teeth of the dates wheel 162.
- the teeth 165 and the notches 163 a can be evenly distributed around the circumference of the mobile 164 and the date disc 163.
- the mechanism of the eighth embodiment illustrated in FIGS. 70 to 76 comprises mounted on a plate 160 a central barrel 161 around which are rotated a wheel dates 162 carrying a date disk 163, a mobile 164 to a tooth 165 and a control wheel 166 comprising four teeth. These three mobiles 162, 164 and 166 are angularly integral with each other. each other and form a first group of concentric mobiles.
- the disc 163 contains the numbers 1 to 31 and inserted between the 31 and the 1 a notch 163a.
- a PTO 167 driven at a rate of one turn per day at midnight by the watch movement is secured to a drive pinion 169 and a 170 drive tooth.
- a transfer pinion 168 is pivoted crazy on the axis 171 PTO 167.
- the drive tooth 170 cooperates with the teeth of thirty-two teeth of the date wheel 162, the drive gear 169 meshes with the tooth 165 of the mobile 164 and the transfer pinion 168 cooperates with the four teeth of the control wheel 166.
- a second group of concentric mobiles cooperating with the mobiles of the first group of mobiles, includes a transmission ring 172 having an internal toothing of forty-eight teeth engaged with the pinion of transfer 168.
- This transmission ring 172 is angularly secured a crown of the duration of months 173 whose internal toothing has three groups of three teeth and a group of two teeth occupying the positions angular period corresponding to February and four isolated teeth located in the angular area corresponding to the 30-day months between each of these groups of two or three teeth.
- the transmission ring 172 has an external toothing of seven teeth, a group of three corresponding to the months of February and four teeth isolated corresponding to the months of thirty days. This transfer crown 172 thus constitutes a second crown of the duration of the months. The crown of the duration of months 173 still has external teeth of forty-eight teeth.
- a third group of mobiles is constituted by a crown of months 175 of an internal toothing of forty-eight teeth and performing a revolution in four years.
- This crown months 175 carries on its upper surface the coded indications A, B, C and S corresponding to one year within a four-year cycle and four series numbers from 1 to 12 corresponding to the months.
- a fourth group of mobiles features crazy rotated on an axis 179 a pinion of eight teeth 180 meshing with the internal toothing of the crown of transmission 172 and a pinion of two teeth 181 meshing with the teeth of the crown of the months 175.
- a fifth group of mobiles is formed by a pinion 190 pivoted on a axis 191 and in engagement with the external toothing of the crown of the duration of the months 173 and cooperating with the external toothing of the transmission ring 172.
- This eighth embodiment of the mechanism operates on the same principle than the other forms of execution described in the foregoing. What differs is that the date wheel 162 has thirty-two teeth and that the disc dates contains the numbers from 1 to 31 plus a sector comprising notch 163a. When this notch 163a is next to a window 182 that has the periphery of the dial, this notch 163a reveals a portion of the upper surface of the crown of 175 months carrying the codes corresponding to the year in a cycle of four and the current month.
- the date wheel 162 is driven by three separate paths.
- this wheel dates 162 is driven at a rate of one step per day by the drive tooth 170 actuated by the PTO 167.
- this wheel dates 162 is driven in the night of 31 1 of each month by the drive pinion 169 and the single tooth 165 of the additional mobile 164 a step further. This corrects the presence of the thirty-second tooth of the wheel of the dates 162 which is therefore advancing a step additional per month between the 31st and the 1st of each month. If the change of date is obtained automatically by the PTO, this process is not visible because it is done in a fraction of a second.
- the date wheel 162 can be driven by the drive pinion 169, the crown of the duration month 173, the pinion 190, the transfer pinion 168, the crown of transmission 172 and the control crown 166 from 1 to 3 additional steps depending on whether the current month is 1, 2 or 3 days shorter than the number maximum of thirty-one days.
- this training can only take place if one of the teeth of the crown of the duration of the months 173 is in position to mesh with the drive pinion 169. This kinematic connection is the catch-up wheel.
- the transmission crown 172 with the seven outer teeth serves as a selector. It gives the months of less than 31 days an impulse to the crown of the duration of months 173 which is then driven by the power take.
- the date wheel 162 could comprise more than an additional tooth, for example four or more.
- the mobile additional 164 has a number of teeth 165 equal to the number of teeth of the date wheel 162.
- the date disk 163 then has a number of notches 163a equal to the number of teeth additional wheels of the dates 162.
- the teeth 165 and the notches 163a can be evenly distributed around the circumference of the mobile 164 and the date disc 163.
- the user when wants to know the year in a four-year cycle and the current month, can have access to this information quickly by rotating the disk of dates of an angular value of at most 1/4 or 1/8 of a turn using the crown of winding.
- This eighth embodiment still has a sixth group of concentric and coaxial mobiles to the first group of mobiles comprising a wheel of the days 192 secured to a tube 193 rotated on the barrel 161 and carrying to its top end a display disc of days 194.
- This disc of days 194 contains, writes radially, the names of the days that appear in a second window of the dial more in the center than that 182 letting appear the date or the code of the year.
- the wheel of days 193 has a toothing of seven teeth cooperating with the pinion of two teeth 194 driven in rotation by the PTO 167.
- This eighth mobile group can be deleted if the name of the days should not to be displayed.
- Jumpers 195, 196, 197 and 198 maintain the angular position of the month crown 175, date wheel 162, transmission crown 172 and the crown of the duration of the months 173 between two actuations successive.
